SUGGESTIONS FOR PRACTICAL WORK IN RURAL ENGINEERING. 
CORRELATIONS. 
1. The practical work should be correlated with the work in 
Mechanic Arts if such a course is given. 
2. If a special course in mechanical drawing is nob given, it will 
be well to give a number of lessons in the subject as preparation for 
the planning of farm buildings and the making of maps. 
3. Much of the work may be correlated with mathematics and 
physics. 
EQUIPMENT. 
A well-equipped shop, either in connection with the school farm 
or the work in mechanic arts, will be very useful. Likewise, the 
equipment of the farm in implements and machinery will be used 
to good advantage. Where no special equipment is provided, the 
class should take advantage of the farms of the students, near-by 
farms, and implement houses. It will be especially important to 
take advantage of such operation as construction of roads and 
buildings, thrashing, drainage, or any work connected with the course 
which may be going on in the vicinity of the school.
